On the subject of corosion, have you guys seen the posts on the main board about spots of rust being found under the seats of the F30? Seems to have affected quite a few people in different locations. I think the official response is that it does not affect the integrity of the seats but still a bit of a concern on a new car.

Have any of you with F30s encountered this?

Yes! I have what look like rust spots under the seats. It's very light and can be wiped off with the finger!
